v. To all whom it may concern?" g I Be it knownthatl, RoBERr'E. JOHNSTON, of' Middletown, Butler county, Ohio, have in- 1 vented certain new and useful Improvements 5 in Cord-Coating Machinery, of which the following is a specification.

This invention relates to machinery for applying to cord a heavy-coatingof wax or other 7 plastic, and for powderingthe exterior of the IO waxed coating", and for cutting thewaxed and powdered cordi ntolengths and packing the same in boxes.

thoroughly understood after a perusal of the following description,'takeninconnectionwith theaccompanying drawings, in which- Figure 1 is a side view, partly in section, of

Balls of the cord are placedin the drawers to the right 'into the melted material and up through the blast-chamber and over the cooling-cylinder,

thence between. the shaping-rolls, thence through'the powderin the powder-box and.

through between the brush-rolls, and thence between the feed-rolls. The machine being started, the cords are drawn forward continu- The nature of the invention will be more,-

ously. The cords aremaintainedim proper tension bythe adjustment of the tension-roll.

'The cords on their passage through the melted waxreceive acoating of the wax, and, in passing, through the blast-chamber and over the a cord-coating machine embodying my ixncooling-cylinder, become morev or less hard ened, afterwhich theyare given a neat exterior form bythe shaping-rolls. They then pass th'roughth'e powder-box and pick up a slight coating of the powder; which preventstheir adhering to each other in the future. The

brush-rolls'remove the surplus powder, and

' the. cords are projected by the feedrolls out upon the shear-table, where at proper intervals they are chopped off by the shear-blade and fall upon the slatted table, whence, by the opening of this table, they are discharged upon the apron, which carries the pieces to itsdeliveryrhopp'er, whence they fall into thepack ing-boxes arranged below the carrier.

The machine is showuas provided for, running six cords at once; "but in practice there will be. provision for not less than twenty-five cords. The material in the meltingwssel is heated by steam or hot air surrounding it in 'thc heating-jacket. There is an immersing "plunger for each individual.-cord..=and these plungers maybe adjusted vertically in a body or independently. The thickness of the'wax .coatingis regulated by -fih6' depth of immersion and the temperature of the wax. A de-- feet in the running of one of the cords may without disturbing the balance by lifting theproper plunger, &c.' The cooling--' cylinder'is kept filledwith ice or other cooling substance, and. the shell of the cylinder is made Ioc double inorderto avoid the presence of sweat upon .the surfaoeof the cy1inder',whieh sweat ywould j tend to "wet the waxed cords before 8K r ached. the 1 powder-box: on shear;

blade is operated by knockers on the feed-rolls, and these knockers can be adjusted to regulate the length of the cutting. The slatted table serves to supportthe cuttings while actually being cut, but after the cutting each slat of the table tips and allows each cutting to fall independently to the carrier. This prevents the adhesion of the ends of the cuttings to the shear-blades,- and forces the cuttings to fall separately and parallel upon the carrier, whereby they are fed nicely into their packingboxes. l

The details of the machine can nowbe comprehendedby the aid of very little description.

In the drawings, t represents the foot of the plungers, which are forked and slotted to receive and guide the cords; S, a rail arranged over the melting-vessel to sustain the plungers,'which are attached adj ustably to it; T,a
